Inkcazo-format MP3 le program ukuguqulwa

Namhlanje, inkoliso ushicilelo ukuba abantu bamamele phantse yonke imihla, thaca ngohlobo iifayile-MP3 jikelele, kuba zezona zixhaphakileyo laye liyathandwa ngokwale fomathi yokugcina ulwazi ephilileyo. Ke kaloku uhlobo olu hlobo lwe data kuya kuxoxwa, imbali codec ngokwayo kunye nemigaqo nokhowudo. Kuya kunikwa amacebiso aluncedo ngokuphathelele indlela ukuguqula MP3-fayile ngenye indlela okanye iifayile MP3 evela uhlobo eyahlukileyo, zahlukile wathi. Kuyinto elula ngokwaneleyo, ke, kuxhomekeke ukusetyenziswa kweenkqubo ezizodwa.

Yintoni i-format MP3?

Ukuza kuthi ga ngoku, bambalwa abantu bacinga into yokuba isandi ukho kule fomati. Ngokusisiseko, ukuba anithanga kungena endle imigaqo ikhowudi, kwanele ukuba kuthi ukuba iinkcukacha ezirekhodiweyo kwifomu zixinaniswe.

Ngaphambili, ifomathi ezingundoqo apho iifayile zomculo ezigcinwe kwaba WAV. Olu lwazi kuthatha isithuba kakhulu kwi hard disk yakho, ibe phezu kwexesha olu hlobo lwe data iye kakhulu engonwabanga. Ngokukodwa, yandikhathaza Ngaloo maxesha xa umculo waqalisa kuhlala elibonakalayo kwi-Internet. Kwaba lelo xesha ke, kwaye kukho ucinezelo imfuneko audio ukunciphisa ubungakanani imithombo. Eneneni, ukuba ukuguqulela ifomathi WAV ukuba MP3, ukonga isithuba uba oqaphelekayo nangoko (umkhondo kuthatha amaxesha 10 isithuba ngaphantsi, ngaphandle ngefomathi entsha sakhiwo lokuba kule nkcazelo, ungenza nokuba ufake iinkcukacha malunga nengoma, umzekelo, igama lomculi, le ngoma, album, ukukhululwa ngonyaka, kwaye ukubeka ezinye iimpawu ezisisiseko zobugcisa kumqhubi).

Kuba lwesakhiwo kwifayile ukuhlangabezana amasimi okubhaliweyo okukhankanyiweyo, ekuthiwa ID3-tags, emva ngokuzalisa lonke ulwazi olunokuvakaliswa zizakuboniswa umdlali window.

Imbali ingenzeka

Kweli hlabathi kukho ukungavisisani ezininzi malunga ngqo odale olu hlobo lwe data. Nangona livunywa ukuba MP3-fomati, ngoko ukuthetha, kukho uhlobo ingqiqo jikelele ngakumbi MPEG, eyasekwa corporation Moving Umfanekiso Iingcali Group, umphuhlisi lweeteknoloji ikhowudi oyinyaniso kwi MP3 kwakukho iqela Fraunhofer Institute, leyo kuqala ecetywayo ukusetyenziswa codec Lame MP3 Encoder. Yaba nguye lowo umgangatho wokuqala kule ndawo.

Oku kwenzeka phakathi kwiminyaka yoo-90, nangona kunjalo, ngoko eli odiyo (iifayile MP3) olunokuveliswa kuphela ngoncedo abadlali software, ngoko ke ukuqaliswa ngokubanzi ubugcisa obutsha yada. Kuphela emva kokuba iye yakhupha zokuqala abadlali basekhaya abadlali eziphathwayo, lo mgangatho waqala ukuba isetyenziswe njengento enye. Noko ke, ngoku a lot of okhuphisana. Elidityaniswe kuphela kunye nemigaqo esisiseko ukhowudo, apho umntu inciphise mali yokuqalisa izinto.

Imigaqo ukhowudo ucinezelo umgangatho wobudlelwane

Eyona nto ibalulekileyo kule nkqubo, xa izinto umthombo ukuba iguqulelwe ifomathi MP3 - a cut yonke into kwinqanaba zendlu indlebe lwabantu alubonwanga. Lwaba ethetha, kwingoma uya kuba izinga isuntswana 320 kbit / s, 128 kbit / s a rhoqo isampuli esemgangathweni 44 100 Hz kwi - ukubona umahluko isandi kunzima. Kungenxa yoko le nto inkqubo ucinezelo liye lancitshiswa iimpawu ezithile odiyo.

Ukuqonda lo mahluko abantu kuphela ngeendlebe sele ethe kakhulu, okanye sandi usebenzisa inkqubo ezikhethekileyo. De facto, ukuba abe format MP3 kwi studio phantse mntu isebenza. Yena ebandakanyekileyo kuphela ibakala kahle lokugqibela post-imveliso, xa zonke iingoma kufuneka ukulungelelanisa ivolyum, ukwenza ukuba kuqheleke ukuba entsimini ukukhulula albham epheleleyo. Kule ayeke kamva.

iimpawu sound Basic

Njengoko yaziwa, naziphi na izinto umsindo enkulu iparameters eziliqela olumisela umgangatho isandi yakhe. Kwaye MP3-format apha akukho ngaphandle. Ezona mpawu zibalulekileyo yobuninzi isampuli kuqwalaselwa (i zixhaphakileyo eqhelekileyo 44,1 kHz), bitrate (for ezisisiseko umgangatho ixabiso owamkelweyo 128 kbit / s) kunye imowudi isandi (mono, kwesitiriyo, asirhawule 5.1, 6.1 okanye 7.1). Ngokubanzi, ukhetho yokugqibela yi hayi kusoloko kuthathelwa ingqalelo, kunye nogxininiso ekugqibeni umgangatho nayiphi track malunga ngaphezu iimpawu ezimbini zokuqala.

Le fomati uqhelekileyo umculo kunye nezinye iifayile eziviwayo, kwaye ubudlelwane phakathi kwabo

Njengoko ngokuba okhuphisana ngqo ifomati MP3 jikelele, namhlanje ukuba ukubala lukhulu. Njengoko kucacile Zakuhamba yokungafani ngokwemiqathango WAV zokugcina yasekhaya njengoko isetyenziswa awusekho isiphelo. Kodwa Studios isandi umsebenzi, yena, ukuze ndithethe, ityala isiseko lo msebenzi. Ingakumbi xa urekhoda vocals okanye izixhobo live. Kuguqulelwa umbandela ebhalwe WAV ukuya MP3 kuphela kwinqanaba lokugqibela.

Noko ke, umculo angamelwa kwezinye iifomati ezithandwayo namhlanje. Umzekelo, ngokufuthi kakhulu (ingakumbi i-Internet) isebenzisa ezifana iintlobo data njengoko Ogg, AIFF, AMR, kunye nabanye abaninzi. Kodwa nowethu yokwenene MP3 iye umsindo entsha ngakumbi ophezulu ezikumgangatho ezifana FLAC. Kakade ke, ukuze MP3 unako ukuzisa zonke iparameters ubuninzi, kodwa umgangatho lokudlala FLAC limi aphezulu kakhulu. Ngaphezu koko, le yifayile eyodwa, nobungcwele lwenzeka ngqo kwi emthondweni ngenxa umdlali isoftware okanye indlu. Ngamanye amazwi, oyimameleyo lengoma nganye ubona ngabanye kodwa uyakwazi ukukheta phakati emkhondweni kwisidlali. Kuba MP3-format, ibiya kubonakala, nathi, ungakwazi ukwenza ifayile eyodwa ngokuhlanganisa kuwo tracks ezimbalwa. Kodwa nantsi enye utshintshe nje ngokukhawuleza phakathi emkhondweni kolu guqulelo asisayi kukwazi (ukuba ukusebenzisa njengesiqhelo fast phambili, nto ngaphezulu).

Noko ke, asiyiyo yonke into embi. Isibakala sokuba zonke iifomati namhlanje eyaziwa umculo okanye evakalayo iincwadi, unako lula ukuguqula phakathi kwabo, nokuba lo gama kugcinwe lokuqala parameters zezinto odiyo. Ngokusekelwe kule kwaye phantse zonke iinkqubo ukuze kungonakali noguqulo isandi kunye umhleli audio ebizwa converters. Nayiphi na iprogram yale hlobo (umhleli MP3 okanye converter) ibhaqa i yoqobo kunye nohlobo lokugqibela lwefayile odiyo, ngokunjalo kucacile, unako ukuvelisa zombini inguqu ngqo kunye nguqu. Makhe ukuchaza lo mzekelo ethile.

Iliza theory lwefayile MP3 kubahleli audio

namhlanje processing emanyelwayo kusetyenziswa iintlobo ezininzi software. Okokuqala, ingqalelo isicelo esinda ezijoliswe ekuthiwa umhleli odiyo. Phakathi abameli ezigqamileyo ingabizwa iingxilimbela ezifana Sony Sound luqine, Sintrillium Cool Hlela Pro, kamva ethengwe ngaphandle ngu Adobe, waliguqula igama layo baye kuvavanywa, Acoustica Mixcraft, Acid Pro kunye nabanye abaninzi.

Umgaqo esebenza ngayo kukuba, ukuze kube lula, nayiphi na inkqubo MP3-audio luhlobo wave odidi, njengoko lalibhekisela ngenxa iifayile-WAV. Le ndlela limisela ukuvela kunye namathuba ezaneleyo ukuhlela izinto erekhodiweyo naluphi na uhlobo aqhelekileyo ngendlela WAV. Ngaphandle kokuba uyakwazi ukwenza imisebenzi esisiseko ukukhuphela, wonqanyulwa, unama, njalo njalo. E., Kuyinto nje yokubangela utshintsho iimpawu oluqukuqelayo kunye isantya sebhithi, singasathethi ukusetyenziswa inani elikhulu yeziphumo ezongezelelweyo, abaqhagamshelwe studio nge iDirectX okanye jikelele host ibhulorho VST.

Xa uhlobo yayo kwecacileyo, ukuguqulela ifomati MP3 ungasebenzisa umgangatho menu ifayile, equlethe umgca "Gcina njenge ...» (Gcina Njenge ...) okanye umsebenzi langoku kwamanye amazwe. Ngoko ke, yonke le nkqubo kuyehla kuphela ukhetho lwe ifomati yokugqibela (apha umzekelo MP3) kwaye isebenze imo irekhodi elo. Kulo mzekelo, ukuguquka kuya kwenziwa ngokuzenzekelayo ugcine lwangoku uqwalaselo iparameters kunye neempawu rhoqo. Andiyithandi uguqulelo sokuqala? Akukho nto lula ukutshintsha ifomati MP3, pre-ezicacisa izicwangciso eziphezulu. Noko ke, nantsi kuyimfuneko ukuze bayithathele ingqalelo enye into: Ukuba umgangatho umbandela ekrwada embi kakhulu, wenze inkqubela ekhethekileyo nkqu izixhobo zobungcali ngeke isebenze. Apha kuyimfuneko ukusebenzisa izixhobo ezikhethekileyo zokubuyiselwa odiyo, ukubandakanyeka iintlobo ngeentlobo okucoca, njalo-njalo. D. A Umntu uninitiated, oko kuya kubangela kobunzima obuninzi.

Njengoko kucacile, akukho akukho mahluko, ukuba nazo - neencwadi ezishicilelwe emacwecweni kwifomathi MP3, umculo, okanye intetho eshicilelweyo nje okanye ingxolo. Hi ndlela leyi, bavumile kucingelwa ukuba iincwadi audio abe isandi wobunjani ophantsi kakhulu. Oku kuyaqondakala, kuba ifayile kufuneka babe ubuncinane isithuba, kwaye iimpawu isandi kulo mbono yokuthetha ngokubanzi, nto kubaluleke kangaka. Ekugqibeleni, oku ukurekhodwa ngobuchule yelicwecwe kweqela elithile?

Noko ke, ukuba usebenzisa eminye imisebenzi eqhelekileyo ngaphandle ulwazi oluthile, ukuze kuzuzwe isiphumo olungileyo kusenokwenzeka, ingakumbi ekubeni kukho itemplates eyakhelwe-ngaphakathi nasiphi na isicelo hlobo, ngokusekelwe apho isenzo esithile. Kakade ke, ukuze kufikelelwe ephilileyo kuya kuba nzima kakhulu okokuqala, kodwa xa ufunda le program baze bafunde ukuba isebenza njani, ngoko ke uya kufana clockwork, yaye oko kuya akayi kuthatha ixesha elide.

Converters audio

Kunye converters audio meko nokuba lula. Iinkqubo le hlobo sele ilungiselelwe ngokukodwa ukuba ukuguqula arekhodiweyo phakathi kwabo ngokukhawuleza kwaye ngaphandle kukubandakanyeka komsebenzisi gca. Ngokungafaniyo umhleli audio, converters, sinokuthi, ukusebenzisa indlela ibhetshi, oko kukuthi, ukuvumela kulandela enye, umzekelo, ukuguqula MP3-fayile ayikho ikopi enye, uze wenze iziqwenga ezimbalwa kwangoko. Kuxhomekeka elikwi isicelo, akunakubakho ukusuka amashumi eziliqela kumakhulukhulu eziliqela.

Kwakhona, lo mgaqo usebenza ngeepakethe software loo ilula. Kufuneka kuphela ukuba ukhethe izinto yokuqala (kwaye lusoloko kunokuba iintlobo yefayile eyahlukeneyo ngokupheleleyo), uze ufake ifomati yokugqibela. Emva koko cinezela iqhosha okhethekileyo ukuqalisa inkqubo, kwaye imveliso umsebenzisi ufumana zonke iifayile luhlobo elinikiweyo. silondolozwe, ngokuqhelekileyo kwenzeka kwifolda emiselwe ngokwezicwangciso isicelo engagqibekanga, kodwa indawo lokusindisa, Kakade ke, uyakwazi ukutshintsha uwedwa. Kwenzeka ukuba, oku kwenzeka ngokufanayo iimpawu ezingundoqo, nto leyo eza kusetyenziswa kwinkqubo yokuguqula. Kodwa nayiphi na inkqubo inika ekuqaleni umsebenzisi iseti ethile nemigangatho zisetyenziselwa iifayili erekhodiweyo uhlobo oluthile. Kananjalo kutshintshwa.

Inzuzo kwezi zicelo kukuba yonke inkqubo yokuguqulwa kangangoko kunokwenzeka zokusebenzisa, nokwenza zonke iinkqubo ezifunekayo ukuze angabi ixesha elininzi. Noko ke, xa uthelekisa nabo umculo okanye umhleli odiyo, ngokwemiqathango zokukhulisa umgangatho isandi elifanayo ingakumbi kusasazeka apha.

umculo sequence

Nantsi olunye uhlobo lwe-software, uninzi kuzo eyakhelwe-ngaphakathi umhleli MP3, WAV njalo njalo .. Ngale ndlela, besebenza ngemigaqo efanayo audiorekatorami, kodwa izakhono zabo thile ngokubanzi.

Okokuqala, kumayelana isibakala sokuba yonke kuqamba umculo anokuba ngamaqhekeza yeentlobo ezahlukeneyo (MP3, MIDI, WAV, Ogg, ithala VST- okanye DX-izixhobo njalo njalo. D.). Emva kokuba ukurekhodwa isandi okanye ebeka amaqela kuzo zonke iingoma, umzekelo, kunye synthesizers virtual, okwenza elisetyenziswa nokugqwesa, ifayili nto ke onokusindiswa ngendlela efunekayo. Kaninzi iba MP3, okanye WAV, okanye ifayile yeprojekthi yenkqubo. Kwezinye izicelo, kukho kwakhona umsebenzi zokurekhodisha phezu disc. Ufuna ukwenza i-CD audio? Akukho ngxaki! Njengoko ngokunjalo umhleli yomsindo kunga imizuzu embalwa ukwenza imisebenzi eyimfuneko kwaye ufumane isiporo imveliso disc kwi CDP format.

Ukuba sithethe malunga iingenelo lolu hlobo isicelo, kuyacaca ukuba nje manyano enye yeefomati eziliqela uze ugcine okanye ukuthunyelwa kwezinye le iqhelekileyo amandla wabo omkhulu. Ukongeza, kufuneka sinikele ingqalelo into yokuba iziphumo eyalekeneyo efanayo okanye ukutshintsha nayiphi parameter lwengoma lwenzeka ngexesha lenene, oko kukuthi, sisiphumo angalibali kuyimfuneko - oko lokumanyelwa kwangoko, umzekelo, ngokuya ezinye izibambo elawula okanye enye indlela. Ngokwendalo, oku yinxalenye encinane kuphela into iiphakheji software bayakwazi enjalo.

Yintoni kufuneka usebenzise?

Ekugqibeleni, siza kumbuzo abazikhethele-software ukusetyenziswa kunye MP3-format, okanye nayiphi na enye, apho isandi kubhaliwe. Njengoko kucacile, ukuba ukuphulaphula eqhelekileyo umculo okanye neencwadi ezishicilelwe ngokwaneleyo kwaye player nabalulamileyo (isoftware okanye "intsimbi"), okanye eyona yesiqhelo DVD-Player.

Ukuguqula iifayile kwezinye iifomati, ngoko ukuthetha, ngokukhawuleza, kuba converters odiyo egqibeleleyo. Kodwa ukuba imveliso kufuneka ukufumana ngokwekristale isandi, nkqu ngokuguqula olunye uhlobo lwefayile ukuya kwenye, ngaphandle software enamandla ezizodwa buyafuneka. Kakade ke, ixesha elithathwayo ukuze ngakumbi, kwaye ngaphandle ulwazi eyodwa ukufumana enye kwizinga eliphezulu MP3-ifayile okokuqala kwaye engenakufunyanwa. Noko ke, ukuba isifundo ngokucokisekileyo umhleli ubuncinane odiyo, singasathethi ke Studios umculo leengcali, umphumo uya kudlula zonke izinto ezilindelweyo.

endaweni yokuba UYobi

Kuhleli ukongeza ukuba ifomathi MP3 apha kucingwe kakhulu elifutshane, kuba xa uphanda, ingakumbi ukuba ukungena iteknoloji restoration kunye nokubuyiselwa nesandi kunye nokusetyenziswa kweemali ukuphucula umgangatho umbandela, ngoko uyakwazi ukubhala yonke into ngodaba.

Kodwa kangangoko ukuqonda isakhiwo MP3-ifomati, ndicinga ukuba abasebenzisi abaninzi baqonde ukuba yintoni na nokuba yintoni na imigaqo ebekwe phantsi uluhlu yayo kunye notshintsho. Ukanti, ukuba sikhangele kwixesha elizayo, xa kunokwenzeka ukuqikelela kuphela ukuba olu hlobo odiyo, egqalwa esezantsi namhlanje, uza kufumana utshintsho olukhulu. Kwaye, kuyabonakala ukuba, ugxininiso engundoqo iya kubekwa kanye ekuphuculeni umgangatho isandi ngaphandle ukwandisa ngokubaluleka ubungakanani iifayile ngokwabo. Noko ke, kuba ngumba ezinjalo kufuneka zonke sizathu, kuba computer ubuchwepheshe obufanayo abaphuhlisa ngesantya bemfuna.
